It looked to me like the spong was a backdrop for the anemeny. SP?
This photo is from my first try at underwater photography. New diver (26 dives) new camera (first time in the water). Olympus C 5000 with internal flash and PT 019 housing. Taken my first time at Cozumel. These are not as good as some on this board but for a first try I am very pleased.
